• People are willing to trust information from – if the sources are credible • Concentration of attention on “elite users” • Different groups of elite users play different parts • Journalists utilize personal social media accounts to “break” news

20 Associated Press Staff Scolded for Tweeting Too Quickly About OWS Arrests The official rules note, "Don’t break news that we haven’t published, no matter the format." (Reuters spells out the same idea plainly in their handbook: "Don't scoop the wire.") Instead of getting "caught in the moment," the AP's freewheeling tweeters are urged in the e-mail to run "sensitive official AP business" through editors and corporate communications. The AP's social media guidelines were recently updated to insist, "Retweets, like tweets, should not be written in a way that looks like you’re expressing a personal opinion on the issues of the day.” http://nymag.com/daily/intel/2011/11/ap-staff-scolded-for-tweeting-about-ows-arrests.

Breaking news guidance for BBC journalists “But we've been clear that our first priority remains ensuring that important information reaches BBC colleagues, and thus all our audiences, as quickly as possible - and certainly not after it reaches Twitter.” http://www.bbc.co.uk/blogs/theeditors/2012/02/twitter_guidelines_for_bbc_jou.html
